植物内生细菌对植物健康的作用

The Role of Plant Endophytes in Plant Health

植物内生菌是一个多样性十分丰富的微生物类群,存在于没有外在感染症状的健康植物组织内,并与宿主植物协同进化.随着研究领域的不断拓宽和研究方法的不断更新,植物内生菌与植物健康的关系以及应用逐渐成为研究热点.本文主要综述了内生细菌的多样性、进入植物组织内的机制以及内生细菌的主要功能及应用,提出了现阶段内生菌研究存在的问题,并展望了内生菌研究的前景.

Plant endophytes represent a microorganism community with abundant biodiversity.They are distributed in healthy plant tissues without external infection symptoms and co-evolve with their host plants.With the continuous expansion of research fields and updating of research methods of plant endophytic bacteria,their relationship with plant health and their application in plant protection have gradually become research hotspots.This paper reviews the diversity of endophytic bacteria,the mechanism of their entry into plants and their main application functions in recent years.Finally,the current challenges faced by endophytic bacteria research are summarized,and its prospect is discussed.
